Thinking beyond your fence

Reading Time: 3 minutes

As a farmer, you can contribute negatively or positively towards the problem of freshwater pollution. If you want to make a positive contribution, what practices are you implementing to do so?

Farmers battle to keep the farm productive

Reading Time: 3 minutes

Farmers are waging a daily war to keep their farm productive. Find out what they are doing on the battlefield to strengthen their allies and win the war.

The “too much of a good thing” effect of nitrogen

Reading Time: 4 minutes

Nitrogen is a nutrient that is crucial for the optimal growth of plants. Its role in plant health may very well be unparalleled, but what happens when it becomes excessive in the soil? Is it “the more the better”, or rather a case of “too much of a good thing”?

Case study: The journey to sustainability

Reading Time: 15 minutes

The SWAN system is composed of soil, water, atmosphere and nutrient components. The best way to show how these integrated and interrelated measures reflect the journey of improving agricultural sustainability is to show a case study of a farm which has become more sustainable over the past five years.

Don’t expect miracle pastures from nitrogen alone

Reading Time: 3 minutes

Nitrogen alone cannot carry the responsibilities of other nutrients in the plant. That is why farmers need to have a balance of all essential plant nutrients in order to archive optimal growth.

A new perspective

Reading Time: 2 minutes

Approaching agriculture in new ways requires new perspectives on how to view things. One of the main differences between conventional and sustainable agriculture is the relative reliance on external inputs.

The potassium problem, or is it a nitrogen problem?

Reading Time: 3 minutes

Due to a lack of soil health, and an imbalance in soil fertility, farmers are relying for too heavily on nitrogen fertiliser for pasture growth. This can actually lead to potassium loss from the soil.

The actual cost of chemical nitrogen fertiliser

Reading Time: 3 minutes

We tend to focus on the localized environmental impact of nitrogen where it is applied, but what about the broader impact associated with its production?

How we are wasting money and nutrients, and negatively impacting the environment

Reading Time: 8 minutes

There is a lot more nutrient cycling taking place than just what is put into the soil through fertiliser, and taken out in grass and eventually milk. In order to develop a more efficient nutrient cycling system, farmers have to take into account the various losses and sources of nutrients.

See your farm as a system

Reading Time: 3 minutes

Nutrients are brought into the farm through the farm gate, and nutrients are removed through the farm gate. The question that needs to be asked is, are there more nutrients brought into, or removed from the farm system?
